プレートワックスはJIST6502には品質として外観、色調、その他の種々の性質が規定されているが、色調については「製造業者の表示どおりでなければならない」とされ、具体的な色調は規定されていない。 Plates wax appearance as quality in JIST6502, color tone, although various other properties are defined, for color is "must be displayed as per manufacturer", specific color is not specified .

プレートワックスは主に義歯の作製に用いられることから歯肉を想定し、ピンク系の色調に着色され、通常、1.0〜2.0mm厚さのプレート状にして供給される。 Plate waxes mainly assumes gingiva since it is used for producing the denture, it is colored shades of pink, usually provided in the 1.0~2.0mm thickness of the plate-shaped. このプレートワックスを用いて人工歯排列や歯肉形成などを行い作製したロウ義歯は、通常、患者の口腔内で試適し、確認した後に石膏埋没、レジン重合などを行って義歯を作製するのが一般的である。 Wax denture fabricated perform artificial teeth Hairetsu and gums formed using this plate wax, usually try-in the mouth of a patient, the gypsum buried after confirming, to prepare a denture performs like resin polymerization generally is a basis.

しかし、現在市販されているプレートワックスは鮮やかなピンク系に着色されていた。 However, plate wax that are currently available on the market had been colored in bright pink. このため、作成されたロウ義歯も生々しい色合いとなり、患者に試適する際に患者を驚かせたり、不快な気分にさせたりすることが多かった。 For this reason, wax denture that has been created also become a vivid hue, or to surprise the patient at the time of try-in patients, were often or to the unpleasant mood.

本発明は患者に不快を感じさせないような色調を種々検討した結果、プレートワックスの色調をL ***表色系での明度L *及び色度a * 、b *を、それぞれ特定範囲となるように調整することにより、患者に不快な気分にさせることなく、また口腔内に装着しても着色違和感のないことを見いだし、下記構成の本発明に想到したものである。 The present invention result of various studies on color tone that does not feel uncomfortable to the patient, the color tone of the plate wax L * a * b * in the colorimetric system lightness L * and chromaticity a *, and b *, respectively specific range by adjusting so that, without the uncomfortable feeling to the patient, also be mounted on the mouth found that no coloration discomfort, in which have arrived to the present invention having the following constitutions.

本発明のプレートワックスは、厚さ1.4mmのプレートを、標準白色板の上に載せて測色したとき、L ***表色系での明度L *及び色度a * 、b *が、 Plates wax of the present invention, the plate thickness of 1.4 mm, when the calorimetric place it on a standard white plate, L * brightness of at a * b * color system L * and chromaticity a *, b * But,

以上のように、天然ワックス及び/又は合成ワックスに、着色料(顔料や染料)を添加して、L ***表色系の明度L *及び色度a * 、b *が、それぞれ特定範囲となるように調整された本発明のプレートワックスを用いて作製したロウ義歯は穏やかな色合いとなり、患者に試適する際に患者を驚かせたり、不快な気分にさせたりすることがない。 As described above, the natural waxes and / or synthetic waxes, with the addition of colorant (pigment or dye), L * a * b * color system of the lightness L * and chromaticity a *, b *, respectively wax denture fabricated using a plate wax of the present invention is adjusted to be the specific range becomes gentle shades, or startled patient upon try-patient, never or to the unpleasant feeling. なお、副次的な効果として、ロウ義歯を作製する際、歯科技工士からは目の疲れが少ないとの評価を得ている。 It should be noted that, as a side effect, making the wax denture, has a reputation to be less tired eyes from the dental technician.

以下、本発明の望ましい態様について説明する。 The following describes preferred embodiments of the present invention. 以下の説明で、配合単位を示す「部」及び「%」は、特に断りのない限り、質量単位である。 In the following description, the blending unit "parts" and "%", unless otherwise specified, is a mass unit.

本発明のプレートワックスは、パラフィンワックス及び/又はマイクロクリスタリンワックスを主成分とし、これにカルナウバワックス、ライスワックス、キャンデリラワックスなどの天然ワックスやポリエチレンワックス等の合成ワックスを混合し軟質、中質、硬質、超硬質などとしたワックス組成物に顔料、染料等の着色料を加えて着色する。 Plate wax of the present invention is mainly composed of paraffin wax and / or microcrystalline wax, to which carnauba wax, rice wax, a mixture of natural waxes and synthetic waxes such as polyethylene waxes such as candelilla wax soft, medium density , hard, colored by adding pigments, colorants such as a dye in a wax composition with such ultra-hard.

そして、その着色に際して、厚さ1.4mmのプレートを標準白色板の上に載せて測色したとき、L ***表色系において、明度L *及び色度a * 、b *が、 Then, when the coloring, when colorimetry put the plate thickness of 1.4mm on the standard white plate, the L * a * b * color system, the lightness L * and chromaticity a *, b * is,
50<L * <70、10<a * <40、a * −10<b * <a * +10 50 <L * <70,10 <a * <40, a * -10 <b * <a * +10
望ましくは、 Preferably,
55<L * <65、15<a * <35、a * −10<b * <a * +10 55 <L * <65,15 <a * <35, a * -10 <b * <a * +10
の要件を満たすようにすることを特徴とするものである。 It is characterized in that to satisfy the requirement.

なお、L ***表色系において、色度a *の値は、「+」が赤の強さ、「−」が緑の強さをそれぞれ示し、色度b *の値は、「+」が黄の強さ、「−」が青の強さをそれぞれ示す。 Incidentally, in the L * a * b * color system, the value of the chromaticity a * is "+" is red intensity, "-" indicates green strength, respectively, the chromaticity b * values, shown by the blue of the strength of each - "+" is yellow strength, "". また、測色に使用する標準白色板は、JIS Z 8722「色の測定方法―反射及び透過物体色」の「5.3.4常用標準白色面」に規定されているものである。 Further, the standard white plate used for colorimetry, JIS Z 8722 - are those defined in "5.3.4 working standard white surface" of the "color measurement method of reflected and transmitted object color".

これらの明度L *及び色度a * 、b *は色彩計、分光測色計などを用いて測定することができる。 These lightness L * and chromaticity a *, b * can be measured using colorimeter, and a spectral colorimeter.

明度L *は顔料、染料の光遮光性や配合量により調整できる。 Lightness L * can be adjusted pigment, the light shielding property and amount of the dye. 明度L *が低すぎては、色調が暗くなり、逆に、明度が高すぎては、色が薄く感じられロウ義歯として用いるには好ましくない。 It is the lightness L * is too low, the color tone is dark, on the contrary, is the lightness is too high, undesirable for use as a row denture color felt thinner.

色度a *は、数値が高くなるにつれて赤方向の色が強くなり、色度a *が高すぎると赤みが鮮やかすぎ、色度b *の数値を調節しても生々しい色となり易い。 Chromaticity a *, the numerical value the color of the red direction becomes stronger as the increases, chromaticity a * is too high, the bright too much redness, likely to become vivid colors by adjusting the numerical value of the chromaticity b *. 色度a *は、数値が低すぎると、赤みがなくくすんだ色となり口腔内に装着したとき、色差違和感を生じ易い。 Chromaticity a * is the number is too low, when mounted in the oral cavity becomes dull color no redness, susceptible to color difference discomfort.

また、色度b *の値が「b * ≦a * −10」であると、色度a *の値が所定値範囲にあっても赤色が強く感じられて好ましくない。 If the value of chromaticity b * is "b * ≦ a * -10" unfavorable values of chromaticity a * is red felt strongly it is in a predetermined value range. また、b *の値が、「b * ≧a * +10」であると、黄色が強く感じられてやはり好ましくない。 In addition, the value of b * is, and is "b * ≧ a * +10", also undesirable yellow is felt strongly. すなわち、色度b *の値がこの範囲内にないと試適に際して違和感が発生し易い。 That is, and without discomfort tends to occur during try-on chromaticity b * values in this range.

下記組成の各ワックス成分を計量するとともに、ワックス成分合計量100部に対して、表1に示す各染料(着色料)を各部数添加して各試料の組成物を調製した。 With metering the wax component of the following composition, with respect to the wax component per 100 parts, were prepared each dye shown in Table 1 (colorant) was added the copies composition of each sample. 各試料組成物を、電気溶解釜に投入し、110℃に設定した温度で20分間加熱、攪拌して完全に溶解させた。 Each sample composition was placed into an electric dissolving tank, heated at a temperature set at 110 ° C. 20 min, and completely dissolved by stirring. 溶解後、直ちにろ過して、厚さ1.4mmのプレート状に成形して着色プレートワックス試料(A〜E及びH〜M)を得た。 After dissolution, immediately filtered to give molded into plates having a thickness of 1.4mm colored plate wax samples (A-E and H to M).

これらの各試料を、標準白色板の上に載せ、ミノルタ色彩色度計CR200を用いて色調を測色した。 Each of these samples, placed on a standard white plate, obtained by measuring the color tone using a Minolta color colored Meter CR200. それらの結果を、表2にL ***表色系で示す。 The results, shown in Table 2 in the L * a * b * color system.

また、表1の各試料(着色プレートワックス)を用いて作製したロウ義歯についての、観察試験の結果は下記の如くであった。 Further, for the wax denture fabricated using the respective samples in Table 1 (colored plate wax), the results of the observational study was as follows.

実施例であるA〜Eを用いたものは、いずれも穏やかな色合いであり、口腔内に試適しても違和感がないものであった。 Those using A~E an embodiment are both mild shade was achieved, there is no discomfort to try-in the mouth.

参考例1、2の市販品F、Gを用いたものは赤色が強く感じられ生々しく、違和感を感ずるものであった。 Commercial products F of Reference Examples 1 and 2, those using G is red is felt strongly vividly, were those that feel a sense of discomfort.

参考例3のHを用いたものは黄色味が強く、参考例4のIは青色味が強くいずれもロウ義歯として違和感があり、参考例5、6のJ、Kのものは市販品F、Gと同様に生々しい赤がやはり感じられるものであった。 Those using H of Example 3 has a strong yellow tint, the I of Reference Example 4 has a sense of incongruity as also brazing denture any strong blue tint, J Reference Examples 5 and 6, a commercially available product F is intended K, Similarly, vivid red and G was intended to be felt again. 参考例7のMを用いたものは色が薄く、やはり色差違和感があるものであった。 Those using the M of Reference Example 7 is thin color, it was those that still there is a color difference discomfort.

本発明の歯科用ベースプレートワックスは穏やかな色合いであり、主としてロウ義歯作製や咬合床、咬合堤等の作製、人工歯の排列などに使うことが出来る。 Dental baseplate wax of the present invention is a mild tint, mainly wax denture fabricated or bite plate, fabricated such occlusion bank, can be used in such Hairetsu of artificial teeth.
